500-850mm Adjustable Length - Supplied with a locking band
The two-part adjustable length offers a degree of flexibility when standard length dimensions are not suitable. All adjustable lengths are supplied with separate insulating material for insertion into the annulus once the installed length has been determined. As the insulation density is installed on site and not controlled by SFL, we recommend that this component is located at least 300mm from any combustible material.
